Findings

Note likely overlap: the ADA 2014 review and Cochrane 2019 pool many of the same trials, and Childsmile's 5 mg/kg threshold likely derives from the same toxicology literature as Whitford.

Applied in version 4 Minor check evidence-independence about article:fluoride-toothpaste-prevents-cavities:3 11 October 2026 by version 2

Version 4 limitations now note that the ADA review likely shares trials with Cochrane, and that Whitford and Childsmile use one shared threshold rather than independent estimates.

Quantify toothpaste's share of young children's total fluoride intake and address whether low-risk-of-bias cohorts show IQ associations at lower exposures.

Applied in version 4 Minor check strongest-objection about article:fluoride-toothpaste-prevents-cavities:3 11 October 2026 by version 2

Version 4 adds the urinary-fluoride objection with toothpaste intake arithmetic (about 0.5 mg/day if a pea-sized amount is fully swallowed twice daily). It also reports NTP's finding that higher-quality studies show associations below 1.5 mg/L.

Revise title and answer: 'far higher intake' contradicts the article's own urinary-fluoride evidence at lower levels; and overall High confidence exceeds the Moderate given for the IQ core.

Applied in version 4 Material check confidence-calibrated about article:fluoride-toothpaste-prevents-cavities:3 11 October 2026 by version 2

Version 4 drops "far higher" from the title and answer, says the low-dose IQ question is unsettled, and lowers overall confidence to Moderate. The rating stays Misleading.

Address the claim's 'neurotoxin' label directly (is fluoride neurotoxic at some dose?) and rate the claim as circulating, not only 'used as directed'.

Applied in version 4 Minor check right-claim about article:fluoride-toothpaste-prevents-cavities:3 11 October 2026 by version 2

Version 4 adds a neurotoxin objection saying fluoride is associated with harm at high exposures and that the dispute is about dose. The method and conclusion now cover both use as directed and swallowing more than recommended.

Address whether EPA's consumer-use finding accounts for combined exposure from many 1,4-dioxane-containing products plus tap water, not laundry alone.

Applied in version 8 Minor check strongest-objection about article:tide-detergent-dioxane-cancer:7 11 October 2026 by version 2

The EPA evidence limitation and the conclusion now say that EPA's published determination does not describe combining laundry exposure with other household products and tap water, citing EDF's critique, so the consumer finding covers product use on its own.

Say that EPA's "no unreasonable risk" means estimated risk below its regulatory benchmark, not zero added risk, so readers don't read False as "no risk at all".

Applied in version 8 Minor check confidence-calibrated about article:tide-detergent-dioxane-cancer:7 11 October 2026 by version 2

A key point, the EPA evidence item and the conclusion now say that "no unreasonable risk" is a regulatory judgement that the estimated risk is acceptable, not zero added risk.

Retitle the hazard item: IARC and NTP both rest on rodent drinking-water bioassays, so they are not two independent lines; and the use-risk finding rests on EPA alone.

Applied in version 7 Minor check evidence-independence about article:tide-detergent-dioxane-cancer:6 11 October 2026 by version 2

"Independent" was removed from the hazard title. Its limitation now says both classifications rest on the same rodent studies, and the conclusion notes that the use-risk finding rests on one agency's modeling, which is part of why confidence is moderate.

Explain why Tide still measured 6.1 to 14 ppm in 2019, six years after P&G's 2013 Prop 65 settlement to reformulate, so readers don't infer the settlement cut exposure.

Applied in version 7 Minor check strongest-objection about article:tide-detergent-dioxane-cancer:6 11 October 2026 by version 2

The legal-limits limitation and the conclusion now say that the settlement's threshold is a daily dose, not a product concentration, and that no published source shows whether the 2019 levels of 6.1 to 14 ppm met it. They also say the measured drop coincides with New York's limits.

Reconsider "No evidence": the article's evidence is affirmative both ways (EPA found no consumer-use risk but a detergent-linked drinking-water cancer risk), which fits "Misleading".

Applied in version 7 Material check rating-follows-evidence about article:tide-detergent-dioxane-cancer:6 11 October 2026 by version 2

Agreed that No evidence did not fit, since EPA's exposure modeling is affirmative evidence. Rather than Misleading, v7 narrows the claim to using Tide (what the article actually tests) and rates it False with moderate confidence. The conclusion explains why and treats the drinking-water pathway as a separate, real concern.

Reword the claim to "Using Tide laundry detergent causes cancer" so it matches what the title, answer and editorial note actually rate.

Applied in version 7 Minor check right-claim about article:tide-detergent-dioxane-cancer:6 11 October 2026 by version 2

The claim now reads "Using Tide laundry detergent causes cancer.", matching the title, answer and editorial note.

Qualify 'does not depend on one institution': Parkes relayed for NASA, LRO is a NASA mission, and NASA controlled sample custody.

Applied in version 4 Minor check evidence-independence about article:apollo-11-moon-landing-evidence:2 11 October 2026 by version 2

The conclusion now names which items still depend on NASA, and non-NASA evidence was added: India's Chandrayaan-2 site imagery and laser-ranging stations in France, Germany, and Italy.

Add an objection addressing whether uncrewed missions could explain the samples, reflectors, and imagery, and answer it with the evidence that crew were present.

Applied in version 4 Material check strongest-objection about article:apollo-11-moon-landing-evidence:2 11 October 2026 by version 2

Added an objection on robotic placement with staged footage, answered with the Luna 16 vs Apollo 11 sample mass, NASA and Chandrayaan-2 orbital imagery, and Parkes reception; added a Van Allen radiation objection with measured crew doses.

Note that the geophysical item's NASA Moon Facts synthesis draws partly on the same Apollo sample and seismic record as the sample-analysis item, or cite primary geophysical studies.

Applied in version 3 Minor check evidence-independence about article:is-the-moon-made-of-cheese:2 10 October 2026 by version 2

Version 3 discloses the overlap rather than adding primary geophysical studies. The editorial note, key points, conclusion, and the geophysical and bulk-density limitations now say the NASA Moon Facts synthesis draws partly on the same Apollo sample and seismic record and on the same NASA mass figures as the density comparison. The conclusion identifies the interior evidence as the least independent and notes the finding does not depend on it. A new method step records the overlap check.
